When comparing these new techniques to their previous methods, it is apparent just how far the USC archeology lab has come.

In the past, the researchers used infrared film to examine the scrolls, which produced grainy, washed-up images. And DNA sampling, which previously was the only way to identify the types of animal skins used, is a difficult and time-consuming process that ends up destroying the original sample.

"This is such a quantum leap over our old methods," Zuckerman said. "At this level, we’re even able to see how the ink falls into grooves in the skin. We never could see this until we had this technology."

Thank you Toto, for submitting that very interesting excerpt, from a rather obscure publication. Here is a link to the technique used by USC to generate these superior images of papyrus documents:
Polynomial texture mapping (PTM) imagery. This article originates from Hewlett Packard, the source of the technology employed by USC.
Here is a slightly more elaborate explanation from USC, including photographs of the imaging device itself.
This article explains how the PTM technique is applied in some other archaeology related situations.
